在所有的中风病例中,半数以上会有警告信号。在中风发生前数小时或数天,常会出现一些先兆现象,如头昏、眩晕、短暂意识模糊、手麻、手足动作不灵、讲话含糊不清、视力模糊、嗜睡、眼结膜出血或视网膜出血等。一旦出现这些先兆,首先必须安静,并立即求医。但是病人往往会忽视或误解这种凶兆,这是很不幸的,因为平均每十个曾短暂脑缺血发作的病人当中,有一个会在一年内患大规模的中风,有三个会在五年内中风。 More than half of all stroke cases have warning signs. A few tridents, such as dizziness, dizziness, brief confusion, hand numbness, hand-foot movements, ambiguous speech, blurred vision, lethargy, conjunctival hemorrhage or retinal hemorrhage often occur hours or days before the stroke Wait. Once these signs have occurred, you must first be quiet and seek immediate medical attention. However, patients often neglect or misunderstand such signs, which is unfortunate because, on average, every 10 patients with a transient ischemic attack will suffer from a massive stroke within one year and three will be within five years Stroke.
